Abstract

La présente invention, selon certains modes de réalisation, concerne un procédé, un dispositif terminal et un appareil de transmission de données en liaison montante, et un procédé, un dispositif de réseau et un appareil d'ordonnancement de données en liaison montante. Selon un mode de réalisation de la présente invention, le procédé de transmission de données en liaison descendante peut consister à recevoir, d'un dispositif de réseau, des informations concernant une position de début de transmission de données en liaison montante sur la bande sans licence; et à déterminer la position de début de transmission de données en liaison montante à partir des informations concernant la position de début de transmission de données en liaison montante, la position de début déterminée de la transmission de données en liaison montante étant associée à une numérologie de porteuse à utiliser. Certains modes de réalisation de la présente invention pourraient permettre la transmission de données en liaison montante sur la bande sans licence dans le système NR et améliorer ainsi les performances du système NR.
